ALBERT T. WHEELER, OF SPRINGVILLE, NEW YORK,

COMBINED VENTILATOR AND CHIMNEY.

SPECIFICATION forming part of Letters Patent No. 226,215, dated. April 6, 1880.

Application filed October 31, 1879.

To all whom it may concern:

Be it known that I, ALBERT T. WHEELER, a citizen of the United States, residing at Springville, in the county of Erie and State of New York, have invented certain new and useful Improvements in Combined Ventilators and Chimneys, of which the following is a specification.

My invention relates to a combined chimney and ventilating-shaft for dwellings or other buildings. Itsobjectistoproducealight,cl1eap, metallic chimney provided with the means for ventilating the rooms through which it passes, a sparkarresting device, and the means for readily cleaning it when required, the whole being adapted to be easily put into a building; and it. consists of a series of double tubes held together by a perforated annular rim at each end, so as to leave an annular ventilating-space between them, the inside tube (or smoke-pipe) projecting through the upperend.

'so as to adapt it to slip into the lower end of another similar tube, in combination with one or more adjustable ventilators and a chimney jacket, as will be more clearly understood by reference to the drawings, in which Figure 1 is a front elevation of a chimney complete; Fig. 2, a vertical section down through the centerof Fig. 1; Fig. S,a horizontal section through line X X, Fig. 1. Fig. 4 represents a bottom view of the chimney;-and Fig. 5 is an enlarged section through a portion of two of the double tubes, showing the manner of connecting them together.

A represents the chimneyjacket. It is provided with a flange, A, at the bottom,by which it may be easily connected to the roof of a building so as to be water-tight, and with a cap at the top, A jointed to the jacket at B, and held when closed, as in Fig. 1, by a springcatch or its equivalent, B It is also provided with a screen, B, on each side, to prevent the sparks from coming out onto the roof.

G represents the inner tube or smoke-pipe, and O the outside tube, leaving the ventilating-space 0 I have shown three sections; but there may be more or less. The tubes 0 G are held together by the annular rims D, having perforations D, to allow a free passage for the air through the ventilating-space O and the sections are jointed together, as shown in Fig. 5, the upper end, 0 of 0 being made to project up high enough to slip into the lower end of the upper section at E, as shown. They may be bolted or otherwise fastened together in any well-known manner.

E (see Fig. 1) represents a ventilator made in the usual way, so it can be closed or opened more or less by means of the handle F.

In the bottom of the chimney, which is in the basement or cellar, I arrange a valve, G, or its equivalent, having a handle, G, to open or close it, for the purpose of removing the ashes or soot or cleaning the chimney. There may be another above, if desired.

The object of-the space 0 is to make the chimney a non-conductor, and thereby avoid the danger of fire. There are as many ventilators E as there are stories in the building and, if desired, a ventilator may be arranged in the cellar.

The ventilators E communicate with the air-space 0 so that the air passes into the ventilator and up through said space, and from section to section, through the perforations D, and out at the top through the openin gs E into the space between the jacketA and the tube or pipe 0, and from thence out at the opening B in the jacket. The smoke passes up through the central tube and out through the screen in the chimney-cap.

I claim as my invention- 1. Acombined chimney and ventilating-shaft consisting of sections comprising each an outer I tube, 0, perforated rims D,inner tube, 0, with projecting end 0 and the ventilator E, sub stantially as set forth.

2. The combination, with the tubes O .O and intervening passage 0 and opening H, of the outer jacket, A, its opening B and the cap A, as set forth.

ALBERT T. WHEELER.
